Like 'em both. Own them both. 30-06 kicks a little harder but Newtons third law dictates as such.
The 30-06 does have a broader bullet selection, but for the most part - we find our pet loads for the 150 / 165 / or 180 gr bullets (whatever) and seldom stray. I have a prestine box of 160 gr noslers for my .270, but can't be bothered because it like's 140's.
Do you like the Granny Smith apple, or the Red Delicious? Pretty much the same, eh?
